I wanted to set in configuration on client HttpWebRequest.Timeout.I was surprised, that MS doesn’t provide it as a part of .Net configuration.(Answer in http://forums.silverlight.net/post/77818.aspx thread: “Unfortunately specifying the timeout is not supported in current version. We may support it in the future release.”) I added it to appSettings section of app.config and read it in the method of My HttpWebRequestHelper class //The Method property can be set to any of the HTTP 1.1 protocol verbs: GET, HEAD, POST, PUT, DELETE, TRACE, or OPTIONS. public static HttpWebRequest PrepareWebRequest(string sUrl, string Method, CookieContainer cntnrCookies) { HttpWebRequest webRequest = WebRequest.Create(sUrl) as HttpWebRequest; webRequest.Method = Method; webRequest.ContentType = "application/x-www-form-urlencoded"; webRequest.CookieContainer = cntnrCookies; webRequest.Timeout = ConfigurationExtensions.GetAppSetting("HttpWebRequest.Timeout", 100000);//default 100sec-http://blogs.msdn.com/b/buckh/archive/2005/02/01/365127.aspx) /* //try to change - from http://www.codeproject.com/csharp/ClientTicket_MSNP9.asp webRequest.AllowAutoRedirect = false; webRequest.Pipelined = false; webRequest.KeepAlive = false; webRequest.ProtocolVersion = new Version(1,0);//protocol 1.0 works better that 1.1 ?? */ //MNF 26/5/2005 Some web servers expect UserAgent to be specified //so let's say it's IE6 webRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)"; DebugOutputHelper.PrintHttpWebRequest(webRequest, TraceOutputHelper.LineWithTrace("")); return webRequest; }Related link:http://stackoverflow.com/questions/387247/i-need-help-setting-net-httpwebrequest-timeoutv
